Q1. How can you decide whether two figures are similar or not?
Ans- You can decide if two figures are similar or not by looking at their:
-General Shape
-Corresponding angels
-Corresponding side lengths
-Ratio Q2. What does a scale factor between two figures tell you?
Ans. The Scale factor tells us in between two figures is that how much have those figures stretched or shrink. Q3. Explain how you can find a scale factor between two similar figures. Use an example to explain your thinking.
Ans 3- Example
Q4. Explain how you can use the scale factor to determine how the area of an enlarged figure compares to the area of the orignal shape.
Ans. The scale factor gets squared to find the area of an enlarged figure compare to the original shape's area.
Summary
This investigation was quite fun. In this investigation we learned how to find the scale factor, how you can know if the figures are similar or not.
